Simcenter STAR-CCM+ 2206 | Release Notes
Important Notes 2206
This section contains important notes that you must become familiar with before using this latest release of
Simcenter STAR-CCM+. If you have questions about any of these important notes, please contact your
Simcenter customer support representative.
New Version Numbering
Beginning with the current release, Simcenter STAR-CCM+ version numbering aligns with the new convention
used by Siemens. The two remaining releases in 2022 are numbered 2206 and 2210, rather than 2022.2 and
2022.3. The release schedule remains unchanged.
Java Upgraded to OpenJDK Version 11.0.13
The Java SDK (Software Development Kit), which is required to compile Java macros, has been upgraded to
OpenJDK v11.0.13 in the current release. Simcenter STAR-CCM+ ships with Eclipse Temurin 11.0.13+8. JDK
builds prior to 11.0.13+8 do not work, but later versions of JDK 11 are allowed (both OpenJDK-based
distributions and Oracle's JDK).
Clang Adopted as New Windows Compiler
Beginning with the current release, the Windows version of Simcenter STAR-CCM+ is now compiled with Clang
11.1. This can result in some cases running up to 20% faster.
Batch Management Systems
Planned End of Automatic Submission (2302)
Support for the submit_starccm+ script is planned to be removed from Simcenter STAR-CCM+ in version
2302.
Support will also be removed for the following -batchsystem sub-options and supporting flags, because
they all depend on the submit_starccm+ script:
• -submit
• -nosubmit
• -writescript
• -logfile
• -template
• -submitfile
• -tmpdir
• -cleanup
Planned End of Support for Load Leveler Scheduler (2302)
Support for the Load Leveler scheduler is planned to be removed from Simcenter STAR-CCM+ in version 2302.
Siemens Digital Industries Software
21
Simcenter STAR-CCM+ 2206 | Release Notes
Memory Reporting: Planned Removal of Deprecated Virtual Memory Report (2210)
The Deprecated Virtual Memory Report (DEPRECATED_VIRTUAL), which is accessed only through macros and
does not appear in the Simcenter STAR-CCM+ UI, is planned for removal in a future release, as early as 2210.
This report type has been deprecated for a long time, as it reports virtual memory in a way which does not
provide an accurate estimate of memory overhead.
The Deprecated Virtual Memory Report is not the same as the Memory report that is accessible in the
Simcenter STAR-CCM+ UI.
Meshing
Planned Removal of Region-Based Meshing (2210)
Region-based meshing is planned to be removed from Simcenter STAR-CCM+ in version 2210.
After the change, when you restore a file using region-based meshing, the following will happen: All volume
meshes that were generated by region-based meshing will be preserved and will be treated as if the volume
mesh was imported into Simcenter STAR-CCM+. You will be able to adjust physics settings and re-run
simulations with the old volume meshes. However you will not be able to change mesh settings or remesh
without creating parts-based mesh operations.
The recommended practice is to use parts-based meshing—see the section "Simcenter STAR-CCM+ > PreProcessing > Meshing > Parts-Based Meshing" in the Simcenter STAR-CCM+ User Guide.
End of Serial Prism Subsurfacer Environment Variable
The serial prism subsurfacer environment variable, which allowed the prism subsurfacer to be created in serial
rather than in parallel, has been removed.
Coordinate Systems: Changes to Input Fields
The response of local coordinate systems to incorrect user entries in the properties has changed.
In previous releases of Simcenter STAR-CCM+, user entries of axis values were automatically adjusted so that
all axes would be normalized and orthogonal with regard to each other. In the current release, incorrect entries
in the new input fields (such as invalid expressions, a zero vector, division by zero, or parallel vectors) result in
error indications in the Simcenter STAR-CCM+ UI. When the input is invalid, the coordinate system either uses
the most recent valid values (for example, in the case of changes to a pre-existing coordinate system), or
attempts to adjust your inputs to generate normalized and orthogonalized values. These automatic attempts
may continue during the simulation session, particularly as the dependency (interaction between the
coordinate system and other objects) changes.
Although the resulting axis values ultimately define a usable coordinate system, and the simulation will still
run, the results are not guaranteed to be correct.
Material Properties
Planned Removal of Anisotropic Material Property Specification Method (2306)
Four material properties—Thermal Conductivity, Electrical Conductivity, Permeability, and Permittivity—
make available the Anisotropic material property specification method in which a full matrix (3 x 3, that is, 9
components) can be specified for the material property coefficients. However, this full specification is
considered not to conform to real materials. A symmetric matrix specification (that is, 6 components) is
Siemens Digital Industries Software
22
Simcenter STAR-CCM+ 2206 | Release Notes
sufficient for a real material. This existing Anisotropic material property specification method is planned to be
deprecated in version 2210 and removed in version 2306.
As a replacement, a new Anisotropic material property specification method (with 6 components) will be
introduced for Thermal Conductivity in version 2210.
Planned Removal of "Anisotropic (Legacy)" Material Property Specification Method for Thermal
Conductivity (2306)
The Thermal Conductivity material property provides the Anisotropic (Legacy) material property
specification method. Using this Anisotropic (Legacy) method, a tensor profile will be specified at the
[Region] > Physics Values level. This tensor profile can have various methods like Axisymmetric Tensor,
Composite Symmetric Tensor, Composite Tensor, Isotropic Tensor, and Principal Tensor. This Anisotropic
(Legacy) material property specification method is planned to be deprecated in version 2210 and removed in
version 2306.
As a replacement, a new Region Scalar Profile material property specification method will be introduced for
the Thermal Conductivity material property in version 2210. This new method will allow a scalar profile to be
specified at [Region] > Physics Values level. This scalar profile will have various specification methods like
Constant, Field Function, Table (Iteration), Table (r), Table (Time), Table (x,y,z), Table (xyz, time), and
User Code.
Materials: Changes to Database Properties
Due to restructuring, some property and method tags are no longer used in material database (.mdb) files.
Some of these discontinued tags need to be replaced, while others do not.
Tags to replace:
Old Property Tags
New Property Tags
<LennardJonesPotential sigma = "4.1" epsilonK =
"209000" />
<LennardJonesCharacteristicLength Value = "4.1" />
<LennardJonesCharacteristicEnergy Value = "209" />
Change the above tags as shown in the column at
right, noting the following:
• LennardJonesPotential should be replaced by
LennardJonesCharacteristicLength and
LennardJonesCharacteristicEnergy.
• The value of sigma should be assigned to
LennardJonesCharacteristicLength.
• The value of epsilonK should be divided by 1000
and be assigned to
LennardJonesCharacteristicEnergy.
Knee Point Flux Density
KneePointFluxDensity
PoissonCoeff
PoissonRatio
ThermalExpansionSolids
ThermalExpansion
If the version of the .mdb file is < 3 (for example, "<!-- Starccm+ Material Data Base version 2.1
-->" ) and it contains the LennardJonesCharacteristicEnergy property tag, its value should be modified as,
NewValue = 1.e-3*OldValue.
Siemens Digital Industries Software
23
Simcenter STAR-CCM+ 2206 | Release Notes
Old Property Tags
New Property Tags
<LennardJonesCharacteristicEnergy value = "71400" /> <LennardJonesCharacteristicEnergy value = "71.4" />
Tags that are discontinued but do not need to be removed:
Although you do not need to remove them from the .mdb files, they are not read into the current version of
Simcenter STAR-CCM+.
• Property tags:
◦ Emissivity
◦ HeatTransferCoef
◦ ThermalDiffusivity
◦ WettingAngle
• Method tags:
◦ ConstantLJPotential
◦ LogPolynomial
Adjoint: Changes to Topology Optimization Solver
Re-normalization Frequency
The default value of the Re-normalization Frequency property of the Topology Optimization > Optimization
Settings node has changed from 20 to 0. The previous default resulted in the normalization being performed
at the first optimization iteration and then every 20 optimization iterations. The new value results in the
normalization being applied only once at the beginning of the first optimization iteration.
Constraints
As part of the improvements to the Topology Optimization solver, property options have changed for the
User-Defined Constraint sub-node (Topology Optimization > Constraints > User-Defined Constraint) and
the Volume Ratio Constraint sub-node (Topology Optimization > Constraints > Volume Ratio Constraint).
In the Type property of these nodes, the Min/Max option has been eliminated. The Equality option has been
added. The new augmented Lagrangian formulation naturally allows for this specific type of constraint.
If a simulation file saved in a previous release of Simcenter STAR-CCM+ contains a Min/Max constraint setting,
it is converted into two separate Minimum- and Maximum-type constraint nodes when opened in the current
release.
Turbulence: Planned Removal of High-Reynolds Number Spalart-Allmaras Model (2302)
The High-Reynolds Number Spalart-Allmaras turbulence model has been hidden in version 2022.1 (only
available through macros) and is planned for removal in version 2302.
Aeroacoustics
Planned End of Convective Option in Ffowcs Williams-Hawkings (FW-H) Modeling
The Convective Acoustic Effects option in FW-H modeling has been deprecated starting in
Simcenter STAR-CCM+ 2020.2 and is planned for removal from a future version.
Deprecation of Standard Newmark Solver Setting (2210)
Siemens Digital Industries Software
24
Simcenter STAR-CCM+ 2206 | Release Notes
The Standard Newmark option has been deprecated starting in Simcenter STAR-CCM+ 2021.3 and is planned
to be removed in version 2210. The recommended practice is to use Newmark Alpha. See the section "Acoustic
Wave Model Reference" in the Simcenter STAR-CCM+ User Guide.
Multiphase
Change to Fluid Film Phase Default Setting
The default setting of the Maximum Volume Fraction property of the Fluid Film phase model Flow Model has
been changed from 0.0 to 0.8.
Consistent Adaptive Mesh Refinement Cell Size Treatment
The treatment of minimum cell size limits by the Free Surface Mesh Refinement criterion has been made
consistent with that of the Adaptive Mesh model. This modification impacts user input in the following way:
• In previous releases, the Free Surface Mesh Refinement criterion did not request refinement for any cells
that are smaller than the specified limit (Adaption Cell Size).
• In the current release, the Free Surface Mesh Refinement criterion does not request refinement for any cells
that would become smaller than the Adaption Cell Size after refinement.
Changes to Default Settings for Mixture Multiphase (MMP) Model
The following changes were made to the default settings in sub-nodes of the Mixture Multiphase (MMP)
model. These new values, which have proven to be more robust, only apply to new simulations. Simulations
that were saved in previous versions of Simcenter STAR-CCM+ will have their model settings restored and not
overwritten by the new defaults:
Sub-Node
Property
Old
Value
New
Value
Large Scale Interface Detection
Number of Cell Layers for Interface Band

Adaptive Interface Sharpening
Number of Cell Layers for Smoothing

3
Derived Parts: Changes to Property Options of Average Surface Part
Due to the adoption of a line integral formulation to compute circumferential averages, the average surface
derived part no longer uses volume when applying weighting. To reflect this change, options for the Weighting
property of this part have been renamed as follows:
• Volume has been renamed to None.
• Volume-Adjusted Scalar Function has been renamed to Scalar Function.
Reports: Change to Computation of Values for Part Surfaces and Subsurfaces
The technique for handling part surfaces and subsurfaces as inputs for Simcenter STAR-CCM+ reports has
changed. In a scenario where both the parent part surface and one or more of its subsurfaces are selected as
inputs to a report computation, the overall report value only accounts for the parent part surface's report value
and ignores the subsurface's report value.
If any of your simulations saved in previous releases have such a combination of inputs in reports, expect
report results to be different in the current release.
Siemens Digital Industries Software
25
Simcenter STAR-CCM+ 2206 | Release Notes
Co-Simulation
End of Older Co-Simulation API Version
Co-Simulation API V4 has been removed. API V6 continues to be supported.
Planned End of WAVE Co-Simulation (2302)
WAVE Co-Simulation is deprecated as of Simcenter STAR-CCM+ 2206 and is planned to be removed in
Simcenter STAR-CCM+ 2302.
Simcenter STAR-CCM+ In-cylinder
Changes to RNG K-Epsilon Defaults
In the current release, the changes to default settings to the RNG (Re-Normalisation Group) K-Epsilon
turbulence model are as follows:
• Buoyancy Production of Dissipation: from Boundary Layer Orientation to Thermal Stratification
• Sarkar Multiplier: from 2.0 to 0.0
Change to Normal Stress Term Default for Turbulence
For reactive-flow calculations of Simcenter STAR-CCM+ In-cylinder, the Normal-Stress (NS) term is now
activated by default. This component is activated when the RKE (Realizable K-Epsilon) or RNG (ReNormalisation Group) K-Epsilon turbulence model is selected.

Heat Transfer: Parts-Based Support Now Available for Actual Flow Dual Stream Heat
Exchanger Model
The UI for the Actual Flow Dual Stream Heat Exchanger model has changed significantly, resulting in several
changes in the user macros. There are seven Heat Exchanger Data Specification options that are currently
supported: UAL Polynomial, UAL Table, UAG Table, Q Table, Q Map, UAL Map, and Volumetric UAL Table. The
macro changes are illustrated for one of these options (Q Map) below, but are applicable to all the seven
options. Dual Stream Heat Exchanger report macros have also changed accordingly, and are illustrated in the

Adjoint: Changes to Topology Optimization Solver
As part of the improvements to the Topology Optimization solver, property options have changed for the
User-Defined Constraint sub-node (Topology Optimization > Constraints > User-Defined Constraint) and
the Volume Ratio Constraint sub-node (Topology Optimization > Constraints > Volume Ratio Constraint).
In the Type property of this node, the Min/Max option has been eliminated. The Equality option has been
added. The new augmented Lagrangian formulation naturally allows for this specific type of constraint.
Each option corresponds to the selection of a specific CSO (Client-Server Object). The change to the Type
property means that the MinMaxConstraintType CSO no longer exists, while the new
EqualityConstraintType CSO has been introduced.
Because the MinMaxConstraintType CSO has been removed, you need to update any macros that use this
CSO with one of the supported types, EqualityConstraintType, MinimumConstraintType, or
MaximumConstraintType, as shown in the following example.

concentration, macro code has changed. Specifically MolarConcentrationProfile has been moved to the
species folder, and for Java macro files to continue working change them as follows:
Previous Release

Current Release
import

Post-Processing: Change to Opening and Closing of Scenes and Plots
Due to improvements in the handling of scene and plot displays, macro code has changed. Instances of
open() should be changed to openInteractive(), and instances of close() should be changed to
closeInteractive().
To improve batch runtime, remove these calls from your macro since they are ignored when
Simcenter STAR-CCM+ runs in batch.

Changes to Use of Displayers
Some redundant scalar displayers have been changed to part displayers. Therefore, in macro recordings in the
current release, scalarDisplayer_XX is now recorded as partDisplayer_XX. Examples of affected
displayers include:
• Intake Valve <N> Displayer 1
• Exhaust Valve <N> Displayer 1
• Cylinder Displayer 1
• Cylinder Piston Surface Displayer 1
• Cylinder Sector Displayer 1
While your existing macros are still expected to work, for maximum reliability, it is recommended that you
update your macro code as shown in the following example:
Previous Release

= ((ScalarDisplayer)
scene_2.getDisplayerManager().getObje

Simcenter STAR-CCM+ 2206 | Release Notes
Known Issues
This section contains a list of known issues that may occur in special circumstances. None of the issues affect
the validity of the results that you obtain with Simcenter STAR-CCM+.
In the following topics, the symbol
is used to identify issues that are new in this release. Only issues
where resolution is related to a third-party product or system provider, and is outside of our control, are listed
here.
A number of these issues pertain to Message Passing Interfaces (MPIs). For more information about MPIs, see
"Supported MPI Implementations" in the Simcenter STAR-CCM+ User Guide.
Contents:
Issues Relevant to All Operating Systems
Issues Relevant to Linux
Issues Relevant to Windows
Issues Relevant to the CAD Clients
Issues Relevant to All Operating Systems
This section contains a list of known issues that affect Simcenter STAR-CCM+ on all operating systems.
MPI 3-Compliant MPIs Strongly Recommended for Flamelet Table Generation in Parallel
In a reacting flow simulation, when you generate a flamelet table in parallel, it is recommended that you use
an MPI that implements the newer MPI 3 standard. Older MPIs that do not implement this standard, or MPIs
with an erroneous implementation, have been found to require significantly more memory during parallel
table generation. This issue affects all MPIs distributed with Simcenter STAR-CCM+ except Open MPI.
Limitation of Co-Simulation with Certain Versions of Simcenter Nastran
Simcenter STAR-CCM+ supports co-simulation with Simcenter Nastran with versions 2020.1 - 1915 , 2020.2 1938 , and 2021.1 - 1965. However, co-simulation with Simcenter Nastran 2020.2 - 1938 gives overdamped
behavior and 2021.1 - 1965 gives wrong displacements when the solid model is solved in the local coordinate
system. Hence it is recommended to use Simcenter Nastran version 2020.1 - 1915 for co-simulation in such
cases.
MPI Issues Found with Simcenter STAR-CCM+ to Simcenter STAR-CCM+ Co-Simulation
Issues have been observed when MPI applications are used to spawn a second parallel Simcenter STAR-CCM+
simulation from an existing parallel simulation.
You are advised to use Resource Manager for this type of co-simulation. See the section "Running a CoSimulation Using Resource Manager" in the Simcenter STAR-CCM+ User Guide.

Simcenter STAR-CCM+ 2206 | Release Notes
Custom Display Scaling Not Supported in Current Release
In the current release, it is recommended that you avoid using your system display settings for scaling
Simcenter STAR-CCM+. Issues have been observed such as blurry fonts, incorrectly registered mouse clicks, and
the inability to select objects in a scene display.
To prevent scaling of Simcenter STAR-CCM+ in Linux, add -jvmargs -Dsun.java2d.uiScale=1.0 to the
command line.
To change the size of Simcenter STAR-CCM+ client fonts, see either of the following:
• All platforms: "Changing the Workspace Font Size" in the Simcenter STAR-CCM+ User Guide
• Windows 10: Preventing Windows from Scaling Simcenter STAR-CCM+
AVX-512 Optimizations on Newer Intel CPUs Can Lead to Spurious Numerical Failures
Simcenter STAR-CCM+ finite element solvers and some meshing modules depend on the Intel Math Kernel
Library (MKL) for performance-critical linear algebra subroutines. The AVX-512 optimizations inside the MKL
library can be too aggressive and cause the linear system solution process to fail even for a valid input.
If your system has an AVX-512 capable Intel CPU and the solver fails to produce a result due to a floating point
exception, you can try setting the environment variable MKL_ENABLE_INSTRUCTIONS to a value of AVX2.
This setting can help to stabilize the system. For example:
• Bash shell: export MKL_ENABLE_INSTRUCTIONS=AVX2
• C shell (csh or tcsh): setenv MKL_ENABLE_INSTRUCTIONS AVX2
This setting configures the MKL library to avoid optimizations that are only appropriate for architectures more
recent than Intel AVX2. For more details, see https://software.intel.com/en-us/mkl-linux-developer-guideinstruction-set-specific-dispatching-on-intel-architectures.
Hyperthreading Should be Disabled on Systems Running Simcenter STAR-CCM+
Siemens Digital Industries Software currently recommends that you disable hyperthreading on systems that
will be used to run Simcenter STAR-CCM+.
Simcenter STAR-CCM+ May Not Run in Conjunction with Synergy
There are reports of Simcenter STAR-CCM+ failing to launch on platforms that use Synergy to share a mouse
and keyboard between platforms. This is due to an open bug in the Java JDK, as reported on the JDK Bug
System: https://bugs.openjdk.java.net/browse/JDK-6322854.
XWindows Can Cause Problems
If you use XWindows software, especially on Windows, to "display" a Simcenter STAR-CCM+ client back to the
local machine from a remote machine, various problems may occur, such as the remote client not starting
correctly or at all. This method of working is not supported by Simcenter STAR-CCM+. You must run the client
directly on your local machine and connect to a remote Simcenter STAR-CCM+ server.
Zero-Sized Files in Some NFS Systems
In some newer NFS systems, if the disk becomes full while you are saving a simulation file, a zero-sized
simulation file is written to the disk. No error message appears.

Simcenter STAR-CCM+ 2206 | Release Notes
Issues Relevant to Linux
This section contains a list of known issues that affect Simcenter STAR-CCM+ on Linux operating systems.
Compatibility Issue with AMD CPUs Based on Zen 3 Microarchitecture
Compatibility issues have been found between the AMD CPUs based on the Zen 3 microarchitecture, such as
the AMD EPYC Milan CPU family, and the currently supported version of the OpenSWR Mesa driver. If you are
using this type of CPU, you are advised to launch Simcenter STAR-CCM+ with the argument -graphics mesa
(at the cost of graphics performance).
UCX 1.8.0 with Special User-Defined Settings Can Lead to Silent Data Corruption
UCX version 1.8.0 has a bug that may cause data corruption when the TCP transport is used in conjunction
with the shared memory transport. In Simcenter STAR-CCM+ with default settings, UCX 1.8.0 is only used in
parallel runs on Mellanox InfiniBand systems predating ConnectX-4 (see Client-Server Setup > Working With
Parallel Servers > Supported MPI Implementations > Using UCX in the Simcenter STAR-CCM+ User Guide), so
this issue may only occur when special user settings are applied to force the use of UCX 1.8.0 with the affected
transports.
During simulation startup, an attempt is made to detect user settings potentially triggering this bug. When
Simcenter STAR-CCM+ does detect such settings, it generates a warning in the Output window.
Libraries Required with Simcenter STAR-CCM+ Client for NX on Linux
To run Simcenter STAR-CCM+ Client for NX on Linux, supported versions of NX must be accompanied by the
installation of the following runtime libraries:
• libGLU.so.1
• libXm.so.4
Without these libraries, an error message appears when an attempt is made to update the geometry.
Latest Workspace Fonts May Require Anti-Aliasing
On some Linux systems, the latest Simcenter STAR-CCM+ workspace fonts have had issues such as blurriness.
The workaround is to activate font anti-aliasing in your operating system settings.
The following example is a workaround for activating anti-aliasing in KDE. It is offered only as an example for a
particular operating system. For instructions on your operating system, refer to its user documentation.
1. Launch KDE settings.
2. Under Look & Feel, click Appearance.
3. Navigate to Fonts.
4. Next to Use Anti-Aliasing, choose Enabled from the drop-down box.
Line Integral Convolution Does Not Work Properly with Intel Graphics Chipsets on
Linux
Vector scenes that are set to display Line Integral Convolution (LIC) do not render properly on Intel graphics
chipsets. This is due to issues with the Intel graphics driver. As a result, LIC is disabled on Intel graphics chipsets
on Linux.

Simcenter STAR-CCM+ 2206 | Release Notes
lmutil: "command not found" Error
On Linux platforms not conforming to the minimum LSB 3.0 (Linux Standard Base) requirement, a command
not found error may appear when attempting to launch lmutil for the FLEXlm licensing. If this occurs, you must
upgrade to LSB 3.0 or higher.
Minimized Dialogs on OpenSUSE
There is a reported issue with OpenSUSE 11.2 where a Simcenter STAR-CCM+ child dialog that is minimized
cannot be immediately reinstated. In this instance, you must first minimize the whole Simcenter STAR-CCM+
GUI, and then maximize it again using the tab in the task bar. The child dialog should reappear after this
operation.
Shared Memory Limits Too Low
Linux workstations are often configured with low limits on the amount of allowable shared memory. This
restricts how much memory can be pinned by the libraries that MPI uses. These libraries can print warning
messages even when only using a single host and they usually indicate the limits are set too low-even if the
library isn't being used. Some example error messages are displayed below:
• Open MPI:
The OpenIB BTL failed to initialize while trying to allocate some locked
memory.
This typically can indicate that the memlock limits are set too low.
For most HPC installations, the memlock limits should be set to "unlimited".
The failure occurred here:
Host: compute_node.example.com
OMPI source: btl_opebib.c:114
Function: ibv_create_cq()
Device: Out of memory
Memlock limit: 32767
The Open MPI Frequently Asked Questions describe how the limits are changed. See the answer to How can
a system administrator (or user) change locked memory limits?.
To resolve these types of issues, set workstations to have high (or preferably unlimited) limits.
Simcenter STAR-CCM+ Viewer Fails to Run If Required Libraries Are Not Found
In the current release, Simcenter STAR-CCM+ Viewer requires the following libraries:
• xkbcommon and xkbcommon-x11—these are standard system libraries that are typically already installed.
• GNU C library version 2.12 or greater
• GIMP Toolkit (GTK+) version 2.20 or greater
If Simcenter STAR-CCM+ Viewer cannot detect these versions, it generates an error message.
If you have these versions installed on your machine and you still get this error, it may be that your
xkbcommon and GTK+ libraries are installed in a location other than the global packages location.
Simcenter STAR-CCM+ Viewer expects to find these libraries in the global packages location, typically /usr.
If you installed GTK+ version 2.20 or greater in a different location:
Siemens Digital Industries Software

Simcenter STAR-CCM+ 2206 | Release Notes
• Add the path to your pkgconfig directory to the PKG_CONFIG_PATH variable. An example bash shell
command is shown below:
% export PKG_CONFIG_PATH=[GTK+_INSTALL_DIR]/lib/pkgxonfig:$PKG_CONFIG_PATH
• Add the path to your lib directory to the LD_LIBRARY_PATH variable. An example bash shell command is
shown below:
% export LD_LIBRARY_PATH=[GTK+_INSTALL_DIR]/lib:$LD_LIBRARY_PATH
Similarly, if you installed the xkbcommon libraries in a different location, add the path to your lib directory to
the LD_LIBRARY_PATH variable. An example bash shell command is shown below:
% export LD_LIBRARY_PATH=[XKBCOMMON_INSTALL_PATH]/lib:$LD_LIBRARY_PATH
Issues Relevant to Windows
This section contains a list of known issues that affect Simcenter STAR-CCM+ on Windows operating systems.
Windows Update KB4598291 Required for Users of Windows 10 Versions 2004 and
20H2
Microsoft has made available a patch, KB4598291, to fix an error in Windows 10 Versions 2004 and 20H2. For
reliable use on Windows of Simcenter STAR-CCM+, especially in parallel, you are advised to make sure your
system includes this fix.
For details, see the page on Microsoft's Support site.
Display Issues May Result from Scaling in Windows 10
In the Display control of Windows 10 Settings, changing the scale of the display may cause a blurry appearance
of Simcenter STAR-CCM+ fonts, as well as interfere with selection of objects in a scene display.
Preventing Windows from Scaling Simcenter STAR-CCM+
1. Right-click the desktop shortcut icon of Simcenter STAR-CCM+ and select Properties.
2. Make the Compatibility tab active.
3. Activate the option Disable display scaling on high DPI settings.
Note:
This option may have a different label, depending on your version of Windows 10. For example,
it may read Override high DPI scaling behavior.
4. Make the Shortcut tab active.
5. In the Target text box, if the path is to a .bat file, replace that path with that of the .exe file, for example:
C:\Program Files\Siemens\16.04.006\STAR-CCM+16.04.006\star\lib
\win64\intel20.1vc14.2\lib\starccm+.exe
6. After you make that change, if the font appears too small in Simcenter STAR-CCM+, increase it as follows:
a. Make the Shortcut tab active.
b. In the Target text box, append -fontsize 18 at the end.
c. If desired, change the value after -fontsize to a different number.

Simcenter STAR-CCM+ 2206 | Release Notes
Some Scene/Plot Exports Fail on Windows When Output Points to Linux Network Folder
When using Simcenter STAR-CCM+ on Windows, if you attempt to export certain data from a scene (hardcopy
image) or a plot (hardcopy image or .csv file) to a location on a Linux host that is mapped to your Windows
drive via Samba sharing, Simcenter STAR-CCM+ generates a message that the selected location is "not
writable". This occurs even when you have full write permission on the Samba drive.
In this situation, it is recommended that you export such files to your local Windows drive.
Exiting Some Screenshot Tools Causes Simcenter STAR-CCM+ Client Exception
When you take screenshots with software such as the Windows 7 Snipping Tool or SnagIt, the
Simcenter STAR-CCM+ client may undergo a fatal error after you exit the screenshot tool. Such an error can
also occur when you reactivate Simcenter STAR-CCM+ after exiting the screenshot tool.
To prevent this error, do one of the following:
• Manually activate an application other than Simcenter STAR-CCM+ before closing the screenshot tool. You
can then switch to Simcenter STAR-CCM+ from the third application without causing the fatal error.
• Minimize the screenshot tool but leave it running.
Context-Sensitive Help Not Compatible with Microsoft Edge
When using Microsoft Edge as the default browser, help pages do not open at the correct location when you
press F1 for a selected node in the simulation tree. To avoid this issue, use an alternative browser such as
Firefox or Google Chrome.
Black Picture Appears in PowerPoint When Playing Movie Files From
Simcenter STAR-CCM+
On some systems, movie (.avi) files recorded using Simcenter STAR-CCM+ may not play back in Microsoft
PowerPoint. This is potentially a problem with incompatible hardware acceleration, as discussed on the
following Microsoft webpage: http://office.microsoft.com/en-us/powerpoint-help/my-movie-doesn-t-playHA010077716.aspx
The recommended response is to turn down your hardware acceleration setting, which is found in the Control
Panel.
Default Scene Lighting
If you have an older graphics card that supports an older version of OpenGL, the default lighting in a scene in
Simcenter STAR-CCM+ can result in hardcopies that are too dark or poorly lit. To improve the output, use a
different lighting setup, such as a headlight.
Internet Explorer May Block Access to the Help System
When using Internet Explorer to access the User Guide, you may see the following message:
To help protect your security, Internet Explorer has restricted this file from
showing active content that could access your computer.
Siemens Digital Industries Software
52
Simcenter STAR-CCM+ 2206 | Release Notes
You can then click for the option to Allow Blocked Content, which will then produce a Security Warning that
says:
Allowing active content such as script and ActiveX controls can be useful, but
active content might also harm your computer.
Are you sure you want to let this file run active content?
To allow this content to run without getting blocked please follow these steps:
1. Open Internet Explorer.
2. Go to the Tools > Internet Options > Advanced tab.
3. Scroll down to the section labeled Security.
4. Activate the Allow active content to run in files on My Computer option.
5. Click OK and then close the Internet Options window.
Warnings About Network Access
If you have a personal firewall (for example, Norton Internet Services) that is set up to warn you about network
access from your computer, you may get warnings about an IP address being accessed on port 47827. This is
caused by the session locator sending a multicast query looking for Simcenter STAR-CCM+ servers on your local
network.
When the client is started without a specified simulation file (the default when Simcenter STAR-CCM+ is started
via the Start > [programs menu] > Siemens Simcenter STAR-CCM+ > Simcenter STAR-CCM+ [version
number] [(build number)] menu on Windows 10), the session locator is started (in case you are attempting to
connect to a running server). If you then open a simulation file or connect to a running server, the session
locator stops. It restarts if you go to the Servers tab in the Simcenter STAR-CCM+ explorer window.
Open that port to prevent the warning, or if you are running from the command line, the -loc argument
prevents the session locator starting.
Issues Relevant to the CAD Clients
This section contains known issues that affect the CAD Clients.
Simcenter STAR-CCM+ Installer Chooses to Install NX Components Even Though NX is
not Installed
On a machine where NX has been installed and subsequently removed, the Simcenter STAR-CCM+ installer
may choose to install the NX components even though the CAD software is no longer present. This is due to
the NX uninstaller not removing all relevant information from the Windows registry.
